[0018] Example 1

[0019] like Figure 1As shown, the present invention provides a syringe for subcutaneous separation specially used in dermatology, comprising a syringe housing 1, a rotating handle 2 is installed on one side of the syringe housing 1, a threaded rod 3 is installed on one end of the rotating handle 2, and the threaded rod 3 extends to the interior of the syringe housing 1, the outer surface of the threaded rod 3 is provided with an external thread, and the inner wall of the syringe housing 1 is provided with an internal thread, which is convenient for pressing down the syringe 4 through the threaded rod 3 by twisting the rotating handle 2, so that the puncture needle 6 at the bottom of the syringe 4 is pressed down and penetrates the subcutaneous tissue of the person, which is convenient for the drug to be input into the blood vessel, a syringe 4 is installed on one end of the threaded rod 3, and a fixing seat 5 is installed on one end of the syringe 4 through the syringe housing 1, and a needle 6 is installed on one side of the fixing seat 5. Arc-shaped hooks 7 are provided on both sides of the fixed seat 5, which can prevent the puncture needle 6 from being accidentally withdrawn from the subcutaneous tissue, thereby enhancing the stability of the puncture needle 6 after it penetrates the human body. A suction cup 8 is provided between the fixed seat 5 and the syringe housing 1, which can make the bottom of the syringe housing 1 close to the skin through the suction cup 8, thereby enhancing the sealing performance and preventing blood from seeping out of the skin. A liquid guide tube 9 is connected to one side of the syringe 4, and a pressure balloon 10 is installed on the liquid guide tube 9. A liquid storage bottle 11 is installed at one end of the pressure balloon 10, and a piston 12 is installed on the liquid storage bottle 11. The piston 12 can be used to store liquid medicine in the liquid storage bottle 11, and by pressing the pressure balloon 10, the pressure of the liquid guide tube 9 can be increased to prevent blood from flowing back.

[0020] Furthermore, the rotating handle 2 is threadedly connected to the syringe 4 through the threaded rod 3, and the syringe 4 can be pressed down through the threaded rod 3 by twisting the rotating handle 2, so that the puncture needle 6 at the bottom of the syringe 4 can be pressed down to penetrate the subcutaneous tissue of the human body.

[0021] The syringe 4 is fixedly connected to the fixing seat 5, so that the handle 2 can be rotated to insert the syringe 4 into the blood vessel through the puncture needle 6.

[0022] The arc-shaped hook member 7 is made of medical silicone material, which is a widely used biomaterial in cosmetic surgery. It has good biocompatibility, is non-irritating to human tissue, non-toxic, has no allergic reaction, and has very few body rejection reactions. It has good physical and chemical properties, and can maintain its original elasticity and softness during contact with body fluids and tissues, and will not be degraded. It is a very stable inert substance that can withstand high temperatures, can be sterilized, and is easy to process and shape. It can prevent harm to the human body, and the arc-shaped hook member 7 can prevent the puncture needle 6 from being accidentally withdrawn from the blood vessel.

[0023] The liquid guiding hose 9 passes through the syringe housing 1 and is fixedly connected to the syringe 4, which facilitates the input of the liquid in the liquid storage bottle 11 from the liquid guiding hose 9 to the syringe 4, thereby facilitating the input of the liquid into the blood vessels for treatment.

[0024] After the syringe 1 is inserted into the syringe 4, the syringe 4 is pushed down, and the syringe 4 is pushed down by the screw threaded rod 3. The syringe 4 is inserted into the subcutaneous tissue of the human body, which is convenient for the injection of the liquid medicine into the blood vessels. The syringe 4 is installed at one end of the screw threaded rod 3. Both sides of the fixing seat 5 are provided with an arc hook 7, which can prevent the puncture needle 6 from being accidentally withdrawn from the subcutaneous tissue, thereby enhancing the stability of the puncture needle 6 after piercing the human body. A suction cup 8 is provided between the fixing seat 5 and the syringe housing 1, which can make the bottom of the syringe housing 1 close to the skin through the suction cup 8, thereby enhancing the sealing performance and preventing blood from seeping out of the skin. A liquid guide tube 9 is connected to the liquid guide tube 9. A pressure balloon 10 is installed on the liquid guide tube 9. A liquid storage bottle 11 is installed at one end of the pressure balloon 10. A piston 12 is installed on the liquid storage bottle 11. The liquid medicine can be stored in the liquid storage bottle 11 through the piston 12, and by pressing the pressure balloon 10, the pressure of the liquid guide tube 9 is increased to prevent blood from flowing back.

[0025] The present invention is capable of maintaining the stability of the needle by providing arc-shaped hook members 7 on both sides of the fixing seat 5. A suction cup 8 is provided between the fixing seat 5 and the syringe housing 1, so that the bottom of the syringe housing 1 can be closely attached to the skin through the suction cup 8, thereby enhancing the sealing performance and preventing blood from seeping to the skin surface. By pressing the pressure balloon 10, the pressure of the liquid guide tube 9 can be increased, which can prevent blood from flowing back and make it more convenient for the cannula to be used for treating patients.
